GPS watches :-

are those watches making use of the Global Positioning Satellites (GPS) to locate such a device very accurately anywhere in the world.

The information can then used in a number of ways depending on the computer/chip and the software in the GPS watch.

Apart from being able to tell you where you are at any given point in time, the information can then be used to monitor speed or distance traveled and give estimates of time to a predefined location.

GPS watches are still generally much larger than the average gents watch, but they are getting smaller and don’t weigh that much on the wrist, but don’t expect to get the same functions and sensitivity to work in adverse conditions as some purpose built hand held navigation devices, although things are improving all the time. Many devices will have difficulty finding satellites from under a thick canopy of leaves or very heavy rain, but this ability is being improved.

It is always difficult to predict how the technology might develop and where it may lead, but at the moment aerial and battery size/power put some limitations on size, as does the readability of the screen, too small and it’s especially difficult to read on the move, but talking GPS watches will no doubt arrive.
